Metabolite Identification
Common NameAmitriptylinoxide
DescriptionAmitriptylinoxide, also known as amioxid-neuraxpharm or equilibrin, belongs to the class of organic compounds known as dibenzocycloheptenes. Dibenzocycloheptenes are compounds containing a dibenzocycloheptene moiety, which consists of two benzene rings connected by a cycloheptene ring. Based on a literature review very few articles have been published on Amitriptylinoxide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Amitriptylinoxide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Amitriptylinoxide is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
